The legal limit for blood alcohol concentration (BAC) while driving in most countries is 0.08%. At this level, your judgment, reaction time, and coordination are significantly impaired, making it dangerous to drive. Some jurisdictions have lower BAC limits, such as 0.05% or even 0.02%. It's important to note that even at BAC levels below the legal limit, your driving ability can be affected, so it's always best to avoid drinking and driving.
